-## Current Diff Flow
-
-1. `capture_diff_slices(alg, &old, &new)` → `Vec<DiffOp>`
-2. `DiffOp::iter_changes(&old, &new)` → `Iterator<Change<T>>`
-3. Requires `T: Hash + Eq + Ord`
-
-## Key Types
-
-```rust
-pub enum DiffOp {
-    Equal { old_index: usize, new_index: usize, len: usize },
-    Delete { old_index: usize, old_len: usize, new_index: usize },
-    Insert { old_index: usize, new_index: usize, new_len: usize },
-    Replace { old_index: usize, old_len: usize, new_index: usize, new_len: usize },
-}
-
-pub struct Change<T> {
-    pub(crate) tag: ChangeTag,
-    pub(crate) old_index: Option<usize>,
-    pub(crate) new_index: Option<usize>, 
-    pub(crate) value: T,
-}
-```
-
-## Algorithm Trait
-
-```rust
-pub trait DiffHook {
-    type Error;
-    fn equal(&mut self, old: usize, new: usize, len: usize) -> Result<(), Self::Error>;
-    fn delete(&mut self, old: usize, old_len: usize, new: usize) -> Result<(), Self::Error>;
-    fn insert(&mut self, old: usize, new: usize, new_len: usize) -> Result<(), Self::Error>;
-    fn replace(&mut self, old: usize, old_len: usize, new: usize, new_len: usize) -> Result<(), Self::Error>;
-}
-```

-## Task: FP Comparison
-
-Add eps/ulps floating point comparison for f32/f64 slices.
-
-### Implementation Points
-
-1. **New comparison trait** alongside existing `PartialEq` requirement
-2. **Algorithm modification** to use FP-aware comparison in core loops
-3. **API surface** for specifying epsilon/ulps parameters  
-4. **Testing** edge cases: NaN, infinity, subnormals, precision boundaries
-
-### Files to Modify
-
-- `src/algorithms/myers.rs` - Core comparison logic
-- `src/algorithms/patience.rs` - Core comparison logic  
-- `src/algorithms/lcs.rs` - Core comparison logic
-- `src/common.rs` - Add FP-aware `capture_diff_slices_fp()`
-- `examples/floating_point.rs` - Usage demonstration
-
-### Example Usage Goal
-
-```rust
-let old = vec![1.0, 2.0, 3.0];
-let new = vec![1.000001, 2.0, 3.1];
-
-// Absolute epsilon
-let ops = capture_diff_slices_fp_eps(Algorithm::Myers, &old, &new, 0.0001);
-
-// Relative ulps  
-let ops = capture_diff_slices_fp_ulps(Algorithm::Myers, &old, &new, 4);
-```
-
-### Testing Strategy
-
-Use existing `insta` snapshot testing framework. Test matrices:
-- Normal values with various epsilon/ulps settings
-- Edge cases: ±0.0, NaN, ±infinity
-- Precision boundaries and subnormal values
-- Mixed normal/edge case arrays
-
-### Status
-
-- [x] CI fixed (Rust 1.66 MSRV)
-- [x] Codebase analysis complete
-- [ ] Design FP comparison API
-- [ ] Implement core FP comparison logic
-- [ ] Add comprehensive tests
-- [ ] Create usage examples
